WebJan 17, 2024 · The hidden state is essentially just an encoding of the information you gave it keeping the time-dependencies in check. Most encoder-decoder networks are trained end to end meaning, when the encoding is learned a corresponding decoding is learned simultaneously to decode the encoded latent in your desired format. WebMar 3, 2024 · Purely abstractly, I suppose you could do something more complicated where you shuffle the data but can compute the initial hidden state for each position in the sequence (e.g. by computing the text up until that point, or else saving & restoring states) but this sounds expensive.
